12-Volt lead/acid storage battery has 12.20 g of PbSO₄(molar mass = 303.3 g), deposited on its electrodes. To recharge it, a ? trickle charger? is attached to the Pb anode that supplies 0.140 amperes of current at a voltage of 13.0 V.

Calculate how much time it would take to convert all the PbSO₄ back into SO₄^2? ions in solution.
